My Sister Stole (Cuckolded) My Fiancé When We Were About To Get Married. But Thanks To The Fact That She Took Him Away, I Am Happy Now.

「Mariabel, I can no longer marry you. I feel bad for you, but I will marry Lillian… whom I truly love and your sister.」

It happened close to the wedding.

Her fiancé, Oswald, suddenly said this to Mariabel.

Next to Oswald was her sister Lillian.

She was smiling at her sister’s despairing figure, as if she were proud of her victory.
